Problems solved by technology
However, since the body uses aluminum profiles and aluminum sheets, the projection welding bolts used on the traditional steel body cannot be used on the all-aluminum body-in-white, because the aluminum itself cannot be used for projection welding, and the connectors and fasteners on the body cannot be welded. Projection welding connection makes it difficult to install and fasten electrical parts or other components on the body

The invention discloses a pressure riveting bolt structure for an all-aluminum body-in-white of an electric vehicle. The pressure riveting bolt (1) includes a screw rod and a bolt head, and the material is steel; the bolt head (3) is a flat cylinder Body, which is provided with a riveting rib (4) on the end face of the screw rod (2); the position of the bolt head (3) is riveted and connected with the aluminum plate of the vehicle body (2), and the aluminum plate of the vehicle body (2) is pressed on the On the described pressure riveting rib (4). Adopting the above-mentioned technical scheme solves the problem that the bolts cannot be welded on the aluminum sheet, realizes the connection of the bolts on the aluminum sheet of the body and forms a pressure riveting structure, the connection is stable and reliable, the bonding strength is high, and the installation capacity is large; the service life is long; due to The cold connection it adopts has lower energy consumption than projection welding, energy saving, environmental protection, and no pollution; the processing and manufacturing are simple, and the riveting operation is convenient.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles and relates to an installation and connection structure of a vehicle body. More specifically, the present invention relates to a pressure riveting bolt structure for an all-aluminum body-in-white of an electric vehicle. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection, especially pure electric vehicles are becoming more and more research hotspots in the automotive field. At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the popularization and application of electric vehicles. [0003] Most of the components on the body frame of the existing electric vehicle are formed by stamping steel plates. The forming process is complicated and the cost is high. The production, assembly and maintenance costs of parts are rela...
